Subject: [PATCH] nbd: add systemd generator and use nbd export names instead
|
|
of port numbers
|
|
|
|
Add a systemd generator for root=nbd:.. so that systemd has a correct
|
|
sysroot.mount unit.
|
|
|
|
Use export names instead of port numbers, because port number based
|
|
exports are deprecated and were removed.
